Description
Technical field
The utility model relates to negative pressure liquid pipeline operating equipment, is specially a kind of negative pressure liquid pipeline sampler.
Background technology
The modern chemical industry technological process is used negative-pressure operation through regular meeting,, subtracts (bearing) as negative reaction and presses rectifying etc., and in these technological processs, reactor, rectification column and the pipeline that is connected thereof all are in and subtract (bearing) pressure condition.If in course of reaction, need, just need to use corresponding sampler, and when sampling, do not change the vacuum tightness of whole reaction system, thereby keep the stability of reaction the detection of taking a sample of the material in the pipeline.Sampling now is generally the normal pressure sampling, and this moment, whole reaction system was a normal pressure, reaction conditions by the people for a change, what be unfavorable for reacting carries out continuously.The sampler that is applicable to the negative pressure liquid pipeline is not at present seen relevant patent report.
The utility model content
Advantages such as the utility model is at the deficiency that exists in the current techniques, and a kind of negative pressure liquid pipeline sampler is provided, and it is convenient, simple in structure, safe in utilization that this device has sampling, is convenient to safeguard, cost is lower.
The technical solution of the utility model is:
A kind of negative pressure liquid pipeline sampler is characterized by this device and comprises visor 6, safe buffering jar 7 and four pipeline A, B, C, D that respectively have a valve; Wherein, pipeline B is a blow-down pipe, and pipeline D is a stopple coupon, and visor 6 links to each other with the bottom of safe buffering jar 7, pipeline A, and B links to each other with the top of safe buffering jar 7, pipeline C, D links to each other with visor 6 by the threeway flange; This device is by pipeline A, and the other end of C is installed in the two ends up and down that vertical liquid main line M goes up valve 5 respectively; Safe buffering jar 7 tops are right cylinder, and the bottom is a cone.
Between described pipeline A, B, C, D and main line M, visor 6 or the safe buffering jar 7 be connected to flange or the threeway flange is connected.
The material of described safe buffering jar 7 is carbon steel, stainless steel or organic glass.
Described pipeline A, B, the valve on C and the D are stop valve or ball valve.
The beneficial effects of the utility model are: have sampling conveniently, and simple in structure, safe in utilization, be convenient to safeguard that advantage such as cost is lower can be implemented in sampling fast in the negative-pressure operation process, do not change simultaneously the vacuum tightness of whole reaction system, made things convenient for middle sampling testing process.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Embodiment:
Be described in detail the utility model below in conjunction with embodiment and accompanying drawing 1 thereof, but the utility model is not subjected to the restriction of embodiment:
A kind of negative pressure liquid pipeline sampler is characterized by this device and comprises the visor 6 that is connected in the pipeline, safe buffering jar 7 and four pipeline A, B, C, D that respectively have a valve; Wherein, pipeline B is a blow-down pipe, and pipeline D is a stopple coupon, and visor 6 links to each other with the bottom of safe buffering jar 7, pipeline A, and B links to each other with the top of safe buffering jar 7, pipeline C, D links to each other with visor 6 by the threeway flange; This device is by pipeline A, and the other end of C is installed in the two ends up and down that vertical liquid main line M goes up valve 5 respectively; Safe buffering jar 7 tops are right cylinder, and the bottom is a cone.
Between described pipeline A, B, C, D and main line M, visor 6 or the sampling jar 7 be connected to flange or the threeway flange is connected.
The material of described safe buffering jar 7 is carbon steel, stainless steel or organic glass.
Described pipeline A, B, the valve on C and the D are stop valve or ball valve.
The material of pipeline A, B, C, D can be according to the different choice carbon steel or the stainless steel of material properties.
In practical operation, as need be to the detection of taking a sample of the material among the main line M, then the concrete dynamic operation step of this device be as follows:
1, after definite valve 1,2,3,4 is closed condition, successively open valve 1 on the pipeline A and the valve 3 on the pipeline C, close the valve 5 on the vertical liquid main line M again, this moment the former main line M that flows through liquid by the road A flow to safe buffering jar 7, through visor 6, pipeline C flows back to main line M again.
2, slowly blind off a line valve 3 on the C, this moment is because the fluid flow that flows into safe buffering jar 7 greater than the flow that flows out, can see that liquid level rises gradually from visor 6.Because each sampling detects and does not need too many feed liquid, thus required when enough taking a sample during full of liquid in the visor 6, open the valve 5 on the main line M at this moment, the valve 3 on the C that blinds off a line fully then, the valve 1 on the A that blinds off a line again.In this step operation, liquid is in flow state all the time, so the negative pressure state of reaction system does not change.
3, open valve 2 on the pipeline B, make safe buffering jar 7 be in atmospheric pressure state, open the valve 4 on the pipeline D again, emit the required feed liquid of sampling, last valve-off 2 and valve 4.
Operation next time repeated for 1,2,3 steps.
As can be seen, how many whole sampling processes mainly by opening and closing the valve realization, uses to the reaction feed liquid, and what are got, and not waste presses to react to whole subtracting (bearing) to have no effect simultaneously.
The utility model negative pressure liquid pipeline sampler and use (bearing) pressure equipment that subtracts of this device not address part and be applicable to prior art.
